Chemical Structure

N-Butyl-2-(methylthio)aniline CAS 581798-34-7 chemical structure

Description

The occurrence of N-Butyl-2-(methylthio)aniline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies N-Butyl-2-(methylthio)aniline (CAS 581798-34-7), a certified reference material (molecular formula C11H17NS, MW 195.32 g/mol) for analytical method development and quality control.

The molecular framework of N-Butyl-2-(methylthio)aniline (C11H17NS) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
